The advanced configuration will allow me to specify an SMTP user name but there is no way to configure the IMAP user name being different from the email-address.
Using New Outlook on Windows for professional communication and productivity
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
This is what I have:
Win 10 using New Outlook that I just installed and using a M365 account with 2 IMAP's using the new Outlook. I did this inside the Control Panel "Mail" . Sorry if I'm missing something just thought I'd share how I did it.
The problem is - it looks like your IMAP account name is an email address from these screencaps. That works fine.
The issue is if you have an IMAP account name that doesn't match your email address.
Nothing you've posted has indicated that you're able to add accounts where the login and email don't match.
Specifically - this screengrab seems to show account logins that are email addresses. These are created via the Add Account settings in Outlook (new), which only accepts email addresses for user names, or are imported on the first run of Outlook (new) from Windows Mail.
This screengrab is the Outlook 365 control panel and isn't connected to Outlook (new).
Thank you for sharing your screengrabs - I appreciate it!! - but I think the problem still remains.
Well, there you are wrong. The username and the email address are different but I'm not showing that info. I use WPX Hosting for my IMAP emails and they do not use same email & username credentials.
it is possible your "email looking" username can be used to setup the account which will eventually work with the intended address.
Example , i can add my account using my ...@onmicrosoft.com address and still eventually use my proper email address (actual domain)
Your provider is working with the email address login, I'm afraid. Behind the scenes.
The screen shot you provided shows that Outlook new is sending the email address as a login.
My email provider does not autoparse the email address as a login. Yours does, apparently.
Thanks, though - you've been very patient with this.
